My re-read of Asimov is still going strong.
So far I've read the following (and in this order):
"Rest of the Robots"
"Caves of Steel"
"Naked Sun"
"Robots of Dawn"
"Robots and Empire"
"The Stars, Like Dust"
"Current of Space"
"Pebble in the Sky" (in progress)
You may note I skipped "I, Robot". I hadn't planned on doing a full scale re-read when I picked up "Rest of the Robots" (which I hadn't read before) and once I had finished it and decided to carry on through the rest of the books, I didn't fancy going back and reading it.
I also realised when reading "The Stars, Like Dust" that it wasn't actually a re-read; I had not read it before.
It is interesting reading in each of the Galactic Empire novels about the radioactivity of Earth, in the light of the events at the end of "Robots and Empire" that explain it in a different way, that is either not known or long forgotten in the Empire novels. We also see Earth's status decline in each subsequent Empire novel, the notion that it originated the human species seem more unbelievable to the residents of the galaxy.
Next up is "Prelude to the Foundation"...
